bios dump lenovo 330-15ast please matherboard mn-b321 rev 1

Hi, i have a Lenovo S145 that after 20 seconds shutdown and restart (it's working correctly on thse 20 seconds)
everything seems ok, but on Vcore inductor ( this is an i3 with just 1 switching power supply for CPU)

there is an output to teh CPU with a spike.. seems that inductor can't handle the input...
replaced the capacitor (330) and the inductor (R15) without any change
any idea? very thank you!

input of the inductor seems as usual... only strange thing is that the upper/lower voltages seems to be 21V (main power line is 19.3) ... but not sure this...

Hi everyone, I replaced this motherboard because it was important to get it working, but it's been with me for a very long time. Now I finally have time to figure out what the problem is,
I've never encountered something like this before;

So a couple of years ago i got a bios update through Lenovo Vantage, so i installed it and bricked my whole BIOS, so i couldn't fix it so i put that ideapad in a box, 3 years later i found that one PC and want to recover it to switch from a 2014 hp laptop to this one.

I found a method to recover the BIOS of many lenovo laptops tha consists in pluging in a USB Flash with the BIOS files and power on the laptop with Fn + R keys pressed until fans go loud and start beeping loud, but nothing worked, so i think filename is wrong, i tried naming the bios file as 07WW.BIN, BIOS.BIN, BIOS.fd,...

[B]Hello dear forum members,[/B]

I have a friend's laptop (Lenovo 330-17-ikb) here that can be switched on (PowerLed lights up), but there is no picture and the fan is not running (CPU cold).
The battery is charging. If you switch off the laptop with the power supply plugged in, it switches on again immediately.
I didn't notice anything on the board when I first opened it. Only one thing, if you don't have the power supply plugged in and then switch it off, it stays off. Strange.

Then I removed the board completely because of strange smell and found a burnt...

Hi.

1) The LVDS cable should be replaced.
